Hey guys I am finally up grading my lt1 so what I got so far is a lt4 hotcam, 1.6 scorpion roller rocker arms, Chevrolet Performance Small Block V8/V6 Individual Valve Springs 12551483, and Trick Flow® Adjustable Pushrod Length Checkers TFS-9000. This is my first build and I was wondering is there anything I am missing. My last question is I want to get my heads ported by a local machine shop but I don't know what specs would work for this set up please help thanks in advance.

 

You might want to consider this source for your head porting... total expertise with the LT1.

What you really need to do is take this in logical order:

- Determine you HP goal

- Determine your budget

- Select the head porting level required for your HP goal

- Match the cam to the heads, considering the end-use of the vehicle - daily driver, 1/4-mile, Auto-X, etc.
